Application led September 18, 1916. Serial No, 120,610.

vention is to provide a plumbers ttingA which will be simple in construction, comparatively cheap in manufacture, and eilicient and durable in operation and use.

Another object of this invention is to provide a plumbers fitting the labor involved in the installation of which will be greatly reduced as compared with plumbers ittings'heretofore in common use.

In the drawings illustrating the principle*- o this invention and the best mode now known to me of applying that principle,

Figure 1 is an elevation of a stack of which my new fitting forms a part; Fig. 2 is horizontal section on the line 2--2 of Fig. l; Fig. 3 is a central, longitudinal, vertical section through a fitting adapted and arranged for the top of the stack; Fig. 4 is a section similar to Fig. 3 but through a itting adapted and arranged for the bottom of the stack; Figs. 5, 6, 7 and 8 are sections on the lines -5, 6-6, 7.-7 and 8 8, respectively, of Figs. 3 and 4; Fig. 9 is a central, longitudinal, vertical section through an intermediate iitting; and Figs. 10 and 11 are sections on the line 10-10 and 11-11, respectively, of Fig. 9.

The fitting a (Fig. 9) is made preferably in the form of a one-piece casting the space within the casing aiof which is divided, by substantially upright partition-walls b into a series oisubstantially vertical depthwiseextending passages or channels c, c", c, cX

the upper ends of which communicate freely with the upper lateral or transverse airpassage d5, and which empty or discharge into the lateral or transversewaste-water At one end or side of each intermediate itting a (Fig. 9), there is an air pipe (or vent-pipe) section f which com mnnicates, through an inner hole or opening with one end of the lateral air-passage d; while, at the opposite end or side of the iitting a, there is a section g of the seil-pipe or waste-pipe, which communicates through an inner hole or opening g with they lateral or transverse waste-water'or soil passage e. The front and back walls h, L, of the casing o* are formed with openings for the en-4 trance of the waste into the fitting, there being, in the form illustratedan inlet open ing into each of the four depthwise-extendmg passages c, c', c and 0*. -lnto each of these openings, there is iitted a waste-pipe leading from one of the plumbing'ixtures; thus, the front wall i1. is formed with an opening z" in which is fitted the discharge end of the waste-pipe j that leads from the sink k and set of washtubs 7c (Fig. 2) to the depthwise-extending channel c,' while the other'or back wall It of the fitting is formed with the openings z', z', z'x, in which are fitted, respectively, ends of the wastepipes y', j, j", that lead from the bath-tub m,

tively. These openings t', z'Q, z", are so placed that each of the waste-pipes j, j', j, jx, communicates with one of the passages c, c', c, cx; thus, the waste-pipe y' leads from the bath-tub m and discharges the wastewater therefrom through the opening i into the passage c; the waste-pipe j conducts the waste-water'from the sink 7c and set of the Watercloset n and washstand o, respec' washtubs le and empties, through the open-l ings e', into the passage c; the waste-pipe,

' j leading from the water-closet n communicates with the passage c through the opening z' and the waste-pipe jx, through which iiows the water discharged by the washstand o, directs the water through the opening ix. 0f course, where one of the lixtures just named (e. g., the washstand o) is not installed, a narrower fitting withv one less depthwise-extending passage may be used; while, where additional fixtures are used, there may be substituted for the fitting c, a wider fitting formed with extra passages with which thewaste-pipe's from the additional fixtures will communicate. The waste is discharged into the lower lateral passage e which is somewhat inclined toward the waste-water pipe or soil-pipe g and communicates therewith through the inner openioo iowing through the passages c, c, c, c",

forms the upper section of the line of airpipe, is closed at its top with the exception of the inner hole or opening ,fx through which the air flows into the upper laterai passage d and thence, through the inner opening g", into the section g of the line of soil-pipe or waste-pipe. A vent pipe y* is connected with the section g and extends through the roof p (Fig. l).

There is shown in the sectional views, Figs. 4, 7 and 8, a fitting a that is particularly adapted and arranged for use as the lowermost fitting of the stack A (Fig. l).

In this form of itt-ing, the inner wall of the section f of the line of air-pipe, which section is illustrated in Fig. 9, is omitted, so that the depthWise-extending passage adjacent. to the air-pipe section merges into the latte-r, whereby the passage c* of Fig. 4 is wider than the corresponding passage e of Fig. 9. The opening 2, which corresponds to the opening i of Fig. 9, is located, in the bottom fitting a, close to the air-pipe side or end thereof (Fig. To the lower end of the waste-pipe section g, there is connected the upper end of a section g of the drain-pipe. The fittings a, a,

a', are connected with one another by means of the pieces r of the line of air-pipe or vent-pipe and by means of the pieces s of the line of wastepipe or soil-pipe, thereby forming the stack A (Fig. l).

It will be obvious to all persons skilled in this art that the plumbers fitting hereinbefore described complies with every requirement of the most advanced sanitary laws and requires for its installation much less labor and material than is needed to install any of the fittings heretofore in common use. Theitting may be made of wrought or cast iron and is adapted for use in apartment houses, oiiice buildings, dwelling houses, stores and buildings used for other purposes. The fittings' a a', a may be connected to the pieces of piping 1', e, by calked joints instead of using the-screw-Joints r', e shown. l

I claimv l. A plumberstting 'including acasin formed near its top witha laterally-exten ing air-passage and near its bottom with a laterally-extending waste-water passage and wise-extending channels the upper ends of which communicate with said air-passage and the lower ends of which communicate wise-extending channels the upper ends of which communicate with said air-passage and the lower ends of which communicate with said wastewater passage; a waste-pipe section arranged within said casing and formed with an opening through which said waste-water passage communicates with said waste-pipe section; and an air-pipe section arranged within said casing and formed with an opening through which said airpassage communicates with4 said air-pipe section; said casing being ormed'with inlet openings arranged to permit the entrance of waste into said channels from outside the fitting.

3. A plumbers fitting including a casing formed near its top with a laterally-extend" ing air-passage and near its bottom with a laterally-extending waste-water passage and betweensaid passages with a series of depthwise-extending channels the upper ends of which communicate with said air-passage and the lower ends of which communicate with said waste-water passage; a waste-pipe section arranged within said casing and formed with openings `through which said passages communicate with said waste-pipe section; and an air-pipe section arranged within said casing and formed with an opening through which said air-passage con municates with said air-pipe section;v saidf'looy casing being formed with inlet openings arranged to permit the entrance of waste into said channels from outside the fitting.
